Background: We examined associations between different chronic morbidities and help-seeking for possible cancer symptoms. Methods: Postal survey of individuals aged >50 years in England. Participants could report prior morbidities in respect of 12 pre-defined conditions. Among patients experiencing possible cancer symptoms we examined associations between specific morbidities and self-reported help-seeking (i.e. contacted versus not contacted a GP) for each alarm symptom using regression analyses...

Objective: To investigate the effect of irradiation to anastomosis from preoperative radiotherapy for patients with rectal cancer by studying the pathological changes. Methods: In this retrospective study, patients enrolled in the FOWARC study from January 2011 to July 2014 in the Sixth Affiliated Hospital of Sun Yat-Sen University were included. In the FOWARC study, enrolled patients with local advanced rectal cancer were randomly assigned to receive either neoadjuvant chemo-radiotherapy or chemotherapy. Among these patients, 23 patients were selected as radiation proctitis (RP)group, who fulfilled these conditions: (1) received neoadjuvant chemo-radiotherapy followed by sphincter-preserving surgery; (2) developed radiation proctitis as confirmed by preoperative imaging diagnosis; (3) had intact clinical samples of surgical margins...

Neo-adjuvant chemoradiotherapy (NACRT) combined with total mesorectal excision (TME) surgery is the main treatment for locally advanced middle-low rectal cancer, and NACRT significantly improves the local control rate of rectal cancer. According to the current guidelines, patients who receive clinical complete response (cCR) after NACRT are recommended for treatment with TME surgery. A few studies have shown that the watch-and-wait (WAW) policy is safe and could ensure anorectal function and quality of life in patients with cCR...

Laparoscopic surgery has been increasingly used in rectal cancer surgery. Though there are still some controversies, most of the research results support that the outcome is similar for rectal cancer patients with either laparoscopic or open surgery, in term of short-term such as safety and efficacy and long-term such as oncologic outcome. Standardization of laparoscopic training together with the comprehensive management concept are the prerequisites of laparoscopic rectal cancer surgery. Those doctors who do minimally invasive surgery should follow the rationale that smaller incision and sphincter preservation are secondary to safety and oncological result of the patients...

BACKGROUND: Combined MET and BRAF inhibition showed clinical benefit in a patient with rectal cancer carrying BRAF(V600E) and MET amplification. However after 4 months, acquired resistance emerged and the patient deceased shortly after disease progression. The mechanism of resistance to this drug combination is unknown. METHODS: We analysed plasma circulating tumour DNA obtained at progression by exome sequencing and digital PCR. MET gene and mRNA in situ hybridisation analyses in two bioptic specimens obtained at progression were used to confirm the plasma data...

BACKGROUND: Acute lower gastrointestinal bleeding is a common reason for emergency hospital admission, and identification of patients at low risk of harm, who are therefore suitable for outpatient investigation, is a clinical and research priority. We aimed to develop and externally validate a simple risk score to identify patients with lower gastrointestinal bleeding who could safely avoid hospital admission. METHODS: We undertook model development with data from the National Comparative Audit of Lower Gastrointestinal Bleeding from 143 hospitals in the UK in 2015...

BACKGROUND: Sedentary behaviour is a potential risk factor for colorectal cancer. We examined the association between sedentary work, based on body position, and colorectal cancer risk in Canadians. METHODS: A working body position category (a. sitting; b. standing and walking; c. sitting, standing, and walking; d. other) was assigned to occupations reported by 1991 Canadian Census respondents based on national occupational counselling guidelines. Adjusted hazard ratios (HRs) and 95% confidence intervals (CI) were estimated for cancers of the colon (overall, proximal, and distal) and rectum in men and women newly diagnosed from 1992 to 2010...

OBJECTIVE: National examination of open proctectomy (OP), laparoscopic proctectomy (LP), and robotic proctectomy (RP) in pathological outcomes and overall survival (OS). BACKGROUND: Surgical management for rectal adenocarcinoma is evolving towards utilization of LP and RP. However, the oncological impacts of a minimally invasive approach to rectal cancer have yet to be defined. METHODS: Retrospective review of the National Cancer Database identified patients with nonmetastatic locally advanced rectal adenocarcinoma from 2010 to 2014, who underwent neoadjuvant chemoradiation, surgical resection, and adjuvant therapy...

This study describes the molecular characterization of an NDM-7 carbapenemase-producing Escherichia coli strain Ec188, recovered from a rectal swab of a male patient who had travelled to Pakistan before his hospitalization at the Hospital del Mar in Barcelona, Spain. The Ec188 isolate, assigned to a new multilocus sequence type ST679, was resistant to all beta-lactams, aminoglycosides (gentamicin, tobramycin, and with reduced susceptibility to amikacin), and ciprofloxacin. The blaNDM-7 gene was located on a 50 kb IncX4 plasmid (pEc188-NDM7), both in the original and transconjugant strains...

Acetylcholinesterase enzymatic histochemistry (AChE EHC), which highlights abnormal cholinergic nerves in the mucosa of aganglionic bowel, has been used for decades to evaluate rectal biopsies for Hirschsprung disease (HSCR). While useful diagnostically, AChE EHC is not compatible with conventional formalin-fixed and paraffin-embedded (FFPE) tissues and is not widely available. The choline transporter (ChT) is a putative alternative marker of cholinergic nerves. ChT immunohistochemistry (IHC) was investigated using FFPE biopsies and resections from patients with confirmed HSCR, as well as appropriate non-HSCR controls...

Given the rising HIV incidence in men who have sex with men (MSM) despite repeatedly proven effectiveness of oral HIV pre-exposure prophylaxis, behaviorally-congruent periodic dosing strategies, such as dosing microbicides as lubricants, are now in demand. Rectal microbicide gel studies largely administer gels using vaginal applicators, which have not been well-received and do not mimic lubricant use. We compared rectal gel manually dosed as lubricant to applicator dosing in five healthy, HIV-negative MSM who received 10 or 3...

Increased perception of visceral stimuli is a key feature of Irritable Bowel Syndrome (IBS). While altered resting-state functional connectivity (rsFC) has been also reported in IBS, the relationship between visceral hypersensitivity and aberrant rsFC is unknown. We therefore assessed rsFC within the salience, sensorimotor and default mode networks in patients with and without visceral hypersensitivity and in healthy controls (HCs). An exploratory resting-state functional magnetic resonance imaging study was performed in 41 women with IBS and 20 HCs...

Screening for colorectal cancer is now integrated into the fabric of healthcare systems across the world, as a wealth of evidence exists as regards its benefits in reducing cancer-specific mortality through the detection of early-stage disease. Options for screening include both endoscopic and stool-based tests, with a majority of countries opting for repeated faecal occult blood screening tests (FOBt). These can be either guaiac-based, as is the current system across the UK, or immunoglobulin-based, as is the case in the accompanying article from Spain...
